"The Fashion Show," which premiered this week, definitely adds some stronger features to the formula. One is audience interaction: At the end of the season, viewers will get to vote for the winner, who will have their designs sold by an unspecified retailer. But the biggest difference is Mizrahi.

When it comes to praise or disproval, he’s issues precise judgements.

"It’s really not a blazer. It’s more of a bolero," he corrects one designer. "I am really offended by you’re your choice in fabrics," he tells another.

Place Mizrahi inside an insurance convention and he’d unfurl endlessly hilarious observations. But when it comes to fashion, spotting a counterfeit is an art form.

Which brings us to Carrie Prejean.

Since the Miss California contestant came out against same-sex marriage rights, the Miss USA Pageant runner-up compares her beliefs to our promising black president's. Both do not favor same-sex marriage and define the union as between "a man and a woman."

I decided to take this matter to a criticism expert.

But first, I wanted to tell the judges about one of this season’s contestants — Andrew Christian, the gay underwear designer who is a contestant on "The Fashion Show." In the first episode, Christoian introduces himself as "The Panty Christ" — which rang a familiar bell...

Mizrahi: That’s crazy. You know, that’s the name of his company, darling. It’s The Panty Christ.

Wait, Andrew Christian is now naming a clothing line called The Panty Christ?

Mizrahi: Yes.

No way. I'd better get a free jockstrap out of it.

Mizrahi: I’m sure you could arrange that, darling.

See? That’s why Bravo is such a groundbreaking network. The producers don’t shy away from fully representing a gay demographic. But what makes "The Fashion Show" remarkably different from "Project Runway" is you, Isaac. Your critiques are scalpel sharp. You’re nothing like nice-guy mentor Tim Gunn. And frankly, I don’t think Michael Kors holds a candle to your ability to pinpoint your criticism so exactingly. Your critiques really get to specifics, which is so constructive. So, Isaac — can I put your acumen to the test?

Mizrahi: Sure

Right now, fashion beauty Miss California Carrie Prejean says her beliefs about same-sex marriage are exactly like Barack Obama’s. Curious — can you spot the difference?

Mizrahi: Wait a minute. Can I spot the difference? Of course, I can spot the difference. Because it’s a lie. Isn’t it? It’s a total lie. I don’t know enough about it, really. You’re putting me … a little bit … I don’t agree with Miss California. And I don’t think Barack Obama is against same-sex marriage. Is he?

Mallis: Barack Obama has the whole country to navigate. And she’s in California — a state where she should be a little more in tune.

Mizrahi: Well that, too. And Barack Obama isn’t running for Miss America. I, I, I … I can’t even comment on Barack Obama or his position on gay marriage. I can’t because I don’t know enough about it. I just think he’s way too smart to be against gay marriage. There has to be a loophole in the way he’s putting it. He’s just way too smart for that. I know that if I was marrying my boyfriend, Arnold, and I invited the Obamas, they would show up. And they would probably get me exactly what I wanted from my registry at Tiffany.

Are you getting ready to pop the question?

Mizrahi: I just know that [Obama] must be playing some kind of political card at the moment.

Mallis: Like the biggest political card in the world.

Mizrahi: Where she is just — I don’t know what she’s playing. She’s playing that "dumb blonde" card.

Mallis: Beauty queen! Beauty queen!

Kelly Rowland: I think she should take responsibility for what she said.

Mizrahi: Well, wait a minute, Kelly. She did. She’s actually out now crusading against gay marriage, if you can believe that. Maybe that’s the difference: I think Barack Obama is not crusading against gay marriage, and she is. And she’s also using God — as, like, you know, her spokesperson, which Barack Obama is not.

I tried to get in one more question, but my line to the conference call was instantly disconnected as a PR rep said, "We’re moving onto the next person in the queue."
